Import Tips
• Obtain Kimberley Process Certificate for all diamond imports to verify conflict-free origin and enable duty-free entry
• Provide detailed documentation proving industrial use, as gem-quality diamonds fall under different subheadings
• Avoid misclassification as worked diamonds (7102.29) by ensuring no polishing beyond bruting
